Contaminated Land Inspection Strategy May 2001 1st Review - Summer 2007 The original report was prepared by Casella Science and Environment Ltd in association with Eden District Council. This review was undertaken by Eden District Council Executive Summary This is the first review of the Contaminated Land Inspection Strategy (referred to as ‘the strategy’) since its initial publication in 2001. The rationale behind the strategy remains constant, however it has been updated to include: • Amendments in legislation and guidance • Updated datasets • Revised assessment process used for sites prioritisation • Progress to date • Timetable of work for 2007-2008 Under new regulations that came into force on 1 April 2000 (Part IIA of Environmental Protection Act 1990) Eden District Council (EDC) was required to inspect land in its district for the purpose of identifying contaminated land. A strategy was submitted to the Department of the Environment Transport and Regions by July 2001. This strategy details how, in light of the characteristics of the area, the authority will take a rational, ordered and efficient approach to this inspection. It should be noted when considering whether land is contaminated or not, the fact that a harmful substance is (in terms of ‘harm’ to human health, to eco-systems or to property or pollution of controlled waters) in, on, or under a piece of land does not itself mean that land is ‘contaminated land’. The source of harm may be present, but unless a possible route (‘plausible pollutant linkage’) exists through which it is likely to cause harm to health, eco-systems, property or cause pollution of controlled waters, the land is not contaminated within the meaning of the Act. In any workable land assessment strategy it is necessary for a system of risk prioritisation to be established. The former uses of a site need to be taken into account as does the local geological and hydrogeological conditions. It is however, the identification of vulnerable receptors and plausible pollutant linkages, which ultimately drives the process. The principal objectives of the strategy are to: • Meet the statutory requirements to produce a strategy; • Use the contaminant-pathway-receptor model as an indication of plausible pollutant linkages. Prioritise and review the condition of the receptors and potential contaminants, identifying immediate concerns and those which may need action in the future; • Inform stakeholders of the Council’s intentions; and • Provide information to the Environment Agency for its report on contaminated land. Eden District Council Contaminated Land Inspection Strategy The Council’s priorities in dealing with contaminated land are to: 1) Protect human health. 2) Protect controlled waters. 3) Protect designated ecosystems. 4) Prevent damage to property. 5) Prevent further contamination of land. 6) Encourage voluntary remediation. 7) Encourage re-use of brownfield land. A map - based land categorisation and prioritisation method is being developed to enable the identification of minimum information requirements and the prioritisation of sites to be inspected in more detail. A programme of assessment over the period 2001 to 2003 was initially undertaken and procedures identified which have taken into account information supplied by the public, business and other organisations; dealing with urgent sites as they arise. The programme also addresses land owned by the Council and land scheduled for development in the Council’s Local Development Framework. The District Council is the lead regulator on contaminated land but, wherever necessary, the Council works in partnership with other organisations, in particular the Environment Agency. The regulations set clear criteria that must be met before land can be formally designated as contaminated land. The Council also maintains a public register in the prescribed form. The strategy is subject to regular review and not a static document. Following on from this initial review, it is proposed that an annual progress report will be published and a full review of the strategy published every five years.

Introduction Under new regulations that came into force on 1 April 2000 (Part IIA of Environmental Protection Act 1990) Eden District Council is required to inspect land in its district for the purpose of identifying contaminated land. The Secretary of State has issued statutory guidance to local authorities on the implementation of Part IIA in England. The Statutory Guidance requires local authorities to take a ‘strategic approach’ in inspecting their areas and to decide and publish this in a written strategy. This document details how Eden District Council will undertake this inspection. 1.1 General Policy of Eden District Council The UK has established a policy and legal framework aimed at minimizing the future incidence of contaminated land; ensuring appropriate action is taken to deal with existing contamination where it poses unacceptable risks to health and the environment; and encouraging the reclamation and recycling of ‘brown field’ land for beneficial use. In the context of sustainable development, appropriate environmental and economic policies are key considerations in developing this Inspection Strategy because they: • Ensure unacceptable risks to human health and the environment are reviewed; to promote a cleaner and healthier environment for local people and wildlife; • Encourage the prudent use of land and social resources; and • Ensure that the cost burdens of undertaking remediation are proportionate, manageable and economically sustainable.
